    Loud and Powerful. Stainless Works 1-7/8" Long Tube Catted Headers removes all the restrictions from the Shelby GT350's exhaust system, delivering a loud exhaust note and a solid increase in power. Adding 22+ RWHP and 18+ RWTQ, Stainless Works Long Tubes are the ideal upgrade for any GT350 owner as they allow the 5.2L Voodoo engine to scream at redline. Mandrel Bent for a no-kink design, Stainless Works Long Tube Headers will uncork your exhaust note and give you a power bump that will throw you back in your seat.

    Lightweight and Road Legal. Using a set of Hi-Flow catalytic converters to filter out your Shelby's emissions, Stainless Works Long Tube Headers are crafted from durable, light, and strong 304 stainless steel. TIG Welded for reinforced strength, Stainless Works Long Tube Headers will hook right up to your factory piping. Stainless Works stands behind their headers by offering a limited lifetime warranty on this exhaust setup.

    Tight Installation. Installing headers on your Shelby GT350 or GT350R can be a little difficult as you will be forced to work in a tight, confined space. While you can complete the installation by jacking your Mustang up, it is much easier to complete if you have access to an engine hoist for lift (your best option).

    Application. Stainless Works 1-7/8" Catted Long Tube Headers are designed to work on 2015-2020 Shelby GT350 and GT350 R Mustangs.

            I put on the Stainless Works Headers and the Corsa resonator delete. My car sounds amazing, especially at 8000 rpm.
